Find out any five activities in your surroundings or daily routine that use prismatic joints. Discuss their functioning in detail.

A prismatic joint is a type of joint that allows linear (straight-line) translational motion along a fixed axis. The following activities use prismatic joints:

1. Opening and closing a drawer: A drawer moves back and forth in a straight line along fixed rails. This sliding movement is an example of a prismatic joint, where motion is restricted to one direction only.
2. Scissors lift or fork lift: A scissors lift moves only upward and downward. The platform rises and lowers through a sliding mechanism, which represents linear motion produced by a prismatic joint.
3. Robotic slider (camera slider): A robotic slider moves a platform or camera along a straight rail. The carriage slides forward or backward, showing the use of a prismatic joint to produce linear motion.
4. Height adjustment of an office chair: When adjusting the height of an office chair, the central column slides vertically. This up-and-down movement along a single axis is an application of a prismatic joint.
5. Sliding door mechanism: A sliding door moves horizontally along a fixed track. The door does not rotate but translates in a straight line, which matches the functioning of a prismatic joint.
